ee'li andi' Wire.I (lompan'y ofY a. corporatioir ofv New;v Jerseirxpp-nennen December zo, 1911;, serrer No. 4233561- scisime.. (ci. zasmfrThis'. invention relates. to bases.' or supporting means'` for furnacesand?, particul'arly,. to' an'. imp'roved base or supporting means formetallurgi cal furnaces, suol-ias box. annealing furnaces.. and.- thelike.

Various types of bases. have.beensuggestedand used for supporting thecharge. in metallurgical furnaces. While. such bases usuallysatisfactorily supported the charge in the furnacei they'weref notdesignedv so as to. permit theI heating gases-toi circulate in and'around the lower portion of. the.- charge toY satisfactorily heatv thesame.. Some bases suggested' were designed so a-stopermit thei gases topass only in. one direction through the base and. around thechargetherein., but such bases did not'permi't maximum circulation of theIgases andl were not entirely satisfactory.

In the presentv invention,1 therey is. provided a-v bas'e formetallurgical furnaces whichl is so con4 structed' that the heatinggasesy pass in. botha; longitudinal and transverse direction through thebase", and. up through the lower portion yof the:

. charge, thereby eliminating the above named diseA advantages.

l Accordingly. it Lis the general. obectnI thefpres` ent invention. toprovide animprovedbase, for useA with metallurgical furnaces and thelike, which is so constructed andl arranged that the heating gases arepermitted to pass both longitudinally and transversely through the baseso that the lower portion of the charge resting thereon is eilicientlyand effectively heated.

It is another object of the invention to provide an improved base foruse with metallurgical furnaces and the like which is simple andinexpensive in its construction and, at the same time, a base which isstrong and rugged.

It is a further object of the invention to provide an improved base foruse with metallurgical furnaces and the like whereby the heating gases.pass entirely underneath and around thelower portion of the charge soas to rapidly penetrate the same, thereby heating the charge to thedesired temperature in a minimum amount of time.

Various other objects and advantages oflthis invention will become moreapparentduring'the course of the following specication and will beparticularly pointed out in the appended claims.

In the accompanying drawings there is shown, for the purpose ofillustration, one embodiment which my invention may assume in practice.

In these drawings:

Figure 1 is a plan view of the improved base of my invention;

Figure. 2r is. an. enr/non of. one. side of the base asshowniniFigure1';

Figureu 3l isy ani elevation of another side. of' my improvedb'asesi'rnilarto Figure. 2.;A

Figure 4 is *ay section-taken on line IV-IV of Figure,1';'and' i Figure5'i's a section taken. on line V-V ofFigure'l.

Referring more particularly to the drawings, the.r improved' base of' myinvention comprises preferably` a cast steel rectangular-shaped bodymember 2 having a top 3,A sid'e and end walls 4;

and a bottom 5'; There is arranged' between the side` and en'dwalls 4'preferably a pluralityL of' spaced apart longitudinally and transverselyextending rib-like portions 6 which are connected together 'to yform anintegral body unit. That is; longitudinally and' transversely extendingriblike portions `l. are arrangedsubstantially perpendicularf to' eachother and' are spaced apart, from eachA othenx There arranged, througheach of the side andV end walls 4` andthe rib-like portions E', aplurality of openings 'l so as to` provide a., plurality-of passagewaysthrough the body member yextending `both longitudinally and transverselythereof and being interconnected with each other.v That is,l thelongitudinally extending, rib-like portions BIare spaced apart. with the)transversely extending rib-like portions having la hole arrangedtherethrough opposite the space between the longitudinally extendingrib-like portions so as to provide a passageway therebetweenwhichextends throughout the length of the body member and the transverselyextending rib-like portions are spaced apart with the longitudinallyextending rib-like portions having an opening ar-' ranged therethroughopposite the space between the transversely extending rib-like portionsso as to provide a passageway between the transversely extendingportions throughout-the width of the body member. It will thus be senthat the'passageways between the longitudinally ex'- tending rib-likeportions and the transversely extending rib-like portions aresubstantially perpendicular to each other and are all interconnected`with each other.

In the top 3 of the body member 2 between each of the rib-like portions6 there is provided an opening 'I which communicates with thetransversely and longitudinally `extending passageways arrangedtherebelow between the transversely and longitudinally extendingrib-like portions. There is arranged in the bottom 4 of the basepreferably a plurality of larger openings 8 which also communicate withboth the longi 'of my invention is placed in the furnace Withwhich it isadapted to be used with the bottom 5 thereof resting on the bottom ofthe furnace. The charge is adapted to be disposed on the top 3 of thebase.

As a result of my invention, it will be seen that there is provided notonly a base whereby the heating gases in the furnace may' circulate bothlongitudinally and transversely of the base in a horizontal plane, butalso a base whereby the' gases may 'circulate from the bottom throughthe top of the base in substantially a vertical plane. Accordingly, itwill be seen that by providing such a construction, the heating gasesmay circulate up through and around the base and the lower portion ofthe charge positioned thereon, thereby effectively heating the lowerportion of the charge with the least amount of heat input.

While I have shown and described one specific embodiment of myinvention, it will'be understood that this embodiment is merely for thepurpose of illustration and description and that various other forms maybe devised within the scope of my invention, as defined inthe appendedclaims.

I claim:

1. A removable base for metallurgical `furnaces and the like comprisinga body member having top, side, end and bottom walls so as to provide abox-like structure, a plurality of longitudinally extending spacedrib-like portions arranged within said body member throughout the lengththereof, a plurality of similar laterally extending spaced rib-likeportions arranged within said body member extending throughout the widththereof and disposed substantially perpendicular to said'longitudinallyextending rib-like portions, both of said longitudinally and laterallyextending rib-like portions extending the height of the body member andintersecting each other, an opening arranged in each of said side wallsand each of said longitudinally extending rib-like portions betweenadjacent laterally extending rib-like portions so as to provideapassageway throughout the width of the body member between each of saidlaterally extending rib-like portions, a similar opening arranged ineach of said end walls and each of said laterally extending rib-likeportions between adjacent longitudinally extending rib-like portions soas to provide a passageway throughout the length of the body memberbetween each of said longitudinally extending rib-like portions wherebya plurality of interconnected passageways are provided throughout boththe length and width of the .body member so as to provide a checker-likearrangement of passageways whereby heating gases may circulate into andaround through all of the openings and passageways of the body member.

2. A removable base for metallurgical furnaces and the like, as dened inclaim l, including an opening arranged' in the top wall between adjacentlongitudinally and laterally extending riblike portions communicatingwith the respective passageways arranged therebelow -in the bodymemberso as to provide a checker-like arrangement of openings in saidtop wall whereby the heating gases may circulate into and around throughall of the passageways and up through the openings in the top of saidbody member.

3. A removable base for metallurgical furnaces and the like, vas definedin claim l, including an opening arranged in the top wall betweenadjacentlongitudinally and laterally extending riblike portionscommunicating with the respective passageways arranged therebelow in thebody member so as to provide a checker-like arrangement of openings insaid top wall, and a plurality of openings arranged in the bottom wallof said body member communicating with the passageways varrangedthereabove between the laterally and longitudinally extending rib-likeportions whereby the heating gases may circulate into and around throughall of the passageways and up through the openings in the top of, saidbody member.
